The Critical Questions- Early Intervention
Dr. Catherine Crowley developed the critical questions over the course of her clinical practice. The Early Intervention version of these questions are more specific to early intervention evaluations. She has found them to be the most effective and valid pieces of information needed by the evaluator in order to distinguish language difference from disorder, especially in culturally and linguistically diverse populations. In addition, this set of questions includes questions supported by research as being the one of the most accurate measures of language disorder (Restrepo, 1998).
